Just received this today and I love it.  It's small, and like other reviews stated, there's not great support on the back and sides.  But I'm using it for my office, and it fits perfectly and is comfortable enough for my purposes.  Further, it pulls out into a sleeper, and that matress is really comfortable.  No painful bars in your back.  You can make the mattress even more plush with extra padding and bedding.  It's an excellent choice if you want additional sleeping space for guests.

Pros: Open up the box and it's ready! The pullout mattress is comfortable.
Cons: I wouldn't recommend it for the primary piece of furniture in your home. The couch on its own,is not overly comfy.
